[0043] The embodiments of the present application provide a refrigerator, its control method, control device, and storage medium to solve the problem that when switching the refrigeration state of an existing dual-system refrigerator, it is necessary to transfer the refrigerant between two refrigeration branches, and when the ambient temperature is high, it is easy to have the problem of slow temperature drop in the compartments. The following will be described in conjunction with the drawings.

[0044] The control method of the refrigerator provided by the embodiments of the present application, the refrigerator includes a compressor 1, a solenoid valve, a freezing evaporator 8, a freezing fan, a refrigerating evaporator 7, and a refrigerating fan. The solenoid valve is connected to the freezing evaporator 8 through a first branch, and the solenoid valve is also connected to the refrigerating evaporator 7 and the freezing evaporator 8 in sequence through a second branch. The solenoid valve can divert the refrigerant to the first branch or the second branch; please refer to Figure 1 , The method includes the following steps:

[0045] Step S101: Obtain the ambient temperature of the refrigerator;

[0046] Step S102: If the ambient temperature is higher than the first preset ambient temperature, control the solenoid valve to divert the refrigerant to the second branch;

[0047] Step S103: Control the opening and closing of the compressor 1, the freezing fan, and the refrigerating fan according to a preset strategy.

[0048] The control method of the refrigerator provided by the embodiment of the present application, when the ambient temperature where the refrigerator is located is relatively high, that is, higher than the first preset ambient temperature, directly controls the solenoid valve to divert the refrigerant to the second branch, so that the refrigerating evaporator 7 and the freezing evaporator 8 are connected in series, and then controls the opening and closing of the compressor 1, the freezing fan and the refrigerating fan according to a preset strategy, that is, controls whether the refrigerating compartment or the freezing compartment starts refrigeration. By directly controlling the refrigerating evaporator 7 and the freezing evaporator 8 to be connected in series when the ambient temperature is relatively high, such as 35 °C, the switching time point of the front refrigeration branch is advanced, that is, it is switched when the ambient temperature has less influence on the refrigeration effect, avoiding the simultaneous existence of the situation where refrigerant migration reduces the refrigeration efficiency and the high ambient temperature reduces the refrigeration efficiency, and further avoiding the problem of slow temperature drop in the compartment when the ambient temperature is relatively high; at the same time, by advancing the switching time point of the front refrigeration branch, the migration of the refrigerant can be completed before the refrigerating compartment has a refrigeration demand, avoiding the influence of the refrigerant migration on the refrigeration efficiency of the refrigerating compartment; and, after the refrigerating evaporator 7 and the freezing evaporator 8 are connected in series, the refrigerant first enters the refrigerating evaporator 7, and after cooling, it enters the freezing evaporator 8, reducing the heat load of the freezing evaporator 8, making it easier for the freezing compartment to achieve deep refrigeration; finally, after the refrigerating evaporator 7 and the freezing evaporator 8 are connected in series, the refrigerant circulates stably on the second branch, reducing the migration loss of the refrigerant on the two branches, enabling the compartment to reach a lower temperature.

[0049] Optionally, step S103 controls the opening and closing of the compressor 1, the freezing fan and the refrigerating fan according to a preset strategy, including: obtaining the freezing temperature of the freezing compartment and obtaining the refrigerating temperature of the refrigerating compartment; if the freezing temperature is higher than the freezing start temperature, then turn on the compressor 1 and the freezing fan; if the compressor 1 is turned on and the refrigerating temperature is higher than the refrigerating stop temperature, then turn on the refrigerating fan; if the refrigerating temperature is lower than or equal to the refrigerating stop temperature, then turn off the refrigerating fan; if the freezing temperature is lower than or equal to the freezing stop temperature, then turn off the compressor 1 and the freezing fan.

[0050] When the freezing temperature is higher than the freezing start temperature, turn on the compressor 1 and the freezing fan, that is, start the refrigeration of the freezing compartment. After the freezing starts to refrigerate, if the refrigerating temperature is higher than the refrigerating stop temperature, then turn on the refrigerating fan, that is, start the refrigeration of the refrigerating compartment. Since the refrigerating evaporator 7 and the freezing evaporator 8 are in series at this time, when the compressor 1 is turned on, the refrigerating evaporator 7 is already in the refrigeration state. Therefore, when the refrigerating temperature is only higher than the refrigerating stop temperature, then turn on the refrigeration of the refrigerating compartment, that is, advance the start time of the refrigerating compartment, without waiting until the temperature of the refrigerating compartment is higher than the refrigerating start temperature, thereby improving the utilization efficiency of the refrigerating evaporator 7, refrigerating the refrigerating compartment in advance, avoiding the problem of slow temperature drop in the refrigerating compartment when the refrigerating compartment has a refrigeration demand due to excessive temperature rise in the refrigerating compartment, making the refrigeration cycle of the refrigerating compartment as synchronous as possible with the refrigeration cycle of the freezing compartment, and improving the refrigeration efficiency of the compressor 1.

[0051] Optionally, after obtaining the refrigeration temperature of the refrigerating compartment, the method further includes: if the refrigeration temperature is higher than the refrigeration start-up temperature, turn on the compressor 1 and the refrigerating fan.

[0052] That is, if the freezing temperature does not reach the freezing start-up temperature, and the refrigeration temperature is higher than the refrigeration start-up temperature due to too long door opening time or other reasons, the compressor 1 and the refrigerating fan are also turned on to start refrigerating the refrigerating compartment, preventing damage to the stored items due to too high temperature in the refrigerating compartment.

[0053] Optionally, if the refrigeration temperature is higher than the refrigeration start-up temperature, after turning on the compressor 1 and the refrigerating fan, the method further includes: if the compressor 1 is turned on and the freezing temperature is higher than the freezing start-up temperature, turn on the freezing fan; if the refrigeration temperature is lower than or equal to the refrigeration shutdown temperature, turn off the refrigerating fan; if the freezing temperature is lower than or equal to the freezing shutdown temperature, turn off the compressor 1 and the freezing fan.

[0054] Optionally, the step if the compressor 1 is turned on and the freezing temperature is higher than the freezing start-up temperature, turn on the freezing fan can be replaced by: if the compressor 1 is turned on and the freezing temperature is higher than the freezing shutdown temperature, turn on the freezing fan. Thus, the refrigeration efficiency of the freezing evaporator 8 and the compressor 1 is improved.

[0055] Optionally, after turning on the compressor 1, the method further includes: if the ambient temperature is higher than the second preset ambient temperature, control the compressor 1 to increase the preset speed based on the current speed; wherein, the second preset ambient temperature is greater than the first preset ambient temperature. In some examples, the first preset ambient temperature can be 32°C, 33°C, 35°C, etc., and the second preset ambient temperature can be 40°C, 41°C, 43°C, etc.

[0056] That is, when the compressor 1 is turned on, if the ambient temperature continues to rise and is higher than the second preset ambient temperature, at this time, due to factors such as the decrease in the heat dissipation efficiency of the condenser 2, the increase in the load of the compressor 1, the decrease in the refrigerant circulation efficiency, and the increase in the burden of the refrigerator insulation layer, the refrigeration efficiency of the refrigerator will be slower. Therefore, the speed of the compressor 1 is increased at this time to make up for the impact of the temperature increase on the refrigeration efficiency.

[0057] Optionally, before controlling the compressor 1 to increase the preset speed based on the current speed, the method includes: calculating the temperature difference between the ambient temperature and the second preset ambient temperature; determining the preset speed according to the temperature difference based on the mapping relationship between the temperature difference and the speed; wherein, the mapping relationship at least includes multiple temperature difference intervals, and each temperature difference interval corresponds to a speed value. It can be understood that the larger the temperature difference, the larger the corresponding speed value.

[0058] Optionally, after step S102 controls the solenoid valve to divert the refrigerant to the second branch, the method further includes: if the refrigerating evaporator 7 meets the defrosting condition, controlling the solenoid valve to divert the refrigerant to the first branch until the defrosting of the refrigerating compartment ends.

[0059] That is, when the refrigerating evaporator 7 needs to be defrosted, in order to prevent the refrigerating evaporator 7 from also refrigerating during the defrosting process, the solenoid valve is controlled to divert the refrigerant to the first branch to prevent the refrigerating evaporator 7 from working during defrosting. After the defrosting of the refrigerating evaporator 7 ends, it is then determined whether to divert the refrigerant to the second branch according to the ambient temperature.

[0060] Optionally, before controlling the solenoid valve to divert the refrigerant to the first branch, the method includes: if the opening duration of the refrigerating fan reaches a preset duration, it is determined that the refrigerating evaporator 7 meets the defrosting condition. Exemplarily, the preset duration can be one hour, that is, when the refrigerating fan is continuously turned on for one hour, it indicates that the current refrigeration duration of the refrigerating evaporator 7 is too long and there may be a risk of frost blockage, so the refrigerating evaporator 7 needs to be defrosted.

[0061] The embodiment of the present application also provides a control device for a refrigerator. Please refer to Figure 2 , the refrigerator includes a compressor 1, a solenoid valve, a freezing evaporator 8, a freezing fan, a refrigerating evaporator 7, and a refrigerating fan.
